Ibrid enpedans pkb

Yon pkb enpedans ibrid se yon tablo sikwi multilayer ki laminates materyèl heterogeneous pandan w ap kenbe egzak kontwòl enpedans atravè kouch, karakterize pa:
1. ibridasyon materyèl: kouch RF (egzanp Rogers RO4000®) + kouch dijital (egzanp FR-4/Megtron ™)
2. Kontinuite enpedans: tolerans tranzisyon mwens pase oswa egal a ± 3% ant materyèl DK disparèt
3. 3 D jesyon enpedans: vètikal via varyasyon enpedans<5%
